The Card

The GeForce RTX 3080 Founders Edition is a new kind of graphics card, both in terms of cooler engineering and design language. You now have one fan on each side of the card—no more backplate. The fan on the left sucks air in from the bottom of the case, routing and exhausting it through the slot-cover opening. The second fan sucks in air from below and pushes it out above the card—near the CPU cooler area, where a case fan is usually installed to exhaust the warm air. Visually, the card looks amazing, with an almost iPhone-like clean design with matte and shiny metal surfaces.

Graphics Card Dimensions

Dimensions of the card are 29 x 11 cm.

Installation requires two slots in your system.

Monitor Outputs, Display Connectors

Display connectivity options include three standard DisplayPort 1.4a and one HDMI 2.1. Interestingly, the USB-C port for VR headsets, which NVIDIA introduced on Turing Founders Editions, has been removed—guess it didn't take off as planned.

The DisplayPort 1.4a outputs support Display Stream Compression (DSC) 1.2a, which lets you connect 4K displays at 120 Hz, and 8K displays at 60 Hz. Ampere can drive two 8K displays at 60 Hz with just one cable per display.

Ampere is the first GPU to support HDMI 2.1, which increases bandwidth to 48 Gbps, to support higher resolutions, like 4K144 and 8K30, with a single cable. With DSC, this goes up to 4K240 and 8K120.

NVIDIA's new NVENC/NVDEC video engine is optimized to handle video tasks with minimal CPU load. The highlight here is added support for AV1 decode. Just like on Turing, you may also decode MPEG-2, VC1, VP8, VP9, H.264 and H.265 natively, at up to 8K@12-bit.

The encoder is identical to Turing, it supports H.264, H.265 and lossless at up to 8K@10-bit.

Graphics Card Power Plugs

The RTX 3080 Founders Edition introduces a new 12-pin power connector. This connector has been talked about a lot recently, it's basically a much more compact solution to provide a lot of power for the card. The 12-pin carries up to 300 W of power, the equivalent of two 8-pin PCIe power cables. Total available power is 375 W (300 W from the 12-pin + 75 W from the PCIe slot). With every Founders Edition, NVIDIA includes a 2x 8-pin to 12-pin adapter cable, so you're good to go and don't need any special adapters.

Multi-GPU Area

The GeForce RTX 3080 does not support SLI. Its bigger brother, the RTX 3090, has SLI support. As both are based on the GA102 GPU, it's purely a segmentation choice. Multi-GPU really isn't supported widely anymore, so it's no big deal.

Teardown

If you've taken a closer look at our photos, you might have noticed that the RTX 3080 Founders Edition has no visible screws! Looks like NVIDIA took inspiration from Apple. This of course complicates the disassembly process, I'll go through it with you, step by step.


First, we have to remove this triangular cover. At the bottom of the V (left side of the first photo), slide your finger underneath the cover and gently lift it up. Do not use any metal tools or you will scratch it. With that done, carefully work your way from one side to the other until the cover comes off. You'll find four screws underneath—remove those.


The four little tabs I've marked are magnetic—what a genius idea, much better than using glue. You can either use sticky tape to pull them up or fine pliers to lift them a bit. I found lifting them from the outside of the card quite easy. Remove the screws underneath.


You can now carefully lift up the cover plate. Take note of the "RTX 3080" text—that's the piece you have to move. Start at the far side, lift it up a bit and tilt it a bit towards the center. There are some thermal pads underneath, so a little bit of wiggling helps to get those off.


Next, remove four screws on the slot cover.


There are still three cables running between the fan assembly and PCB. The first one, J802, uses a slide-lock mechanism. Use a fine screwdriver to push the silvery metal cover away from the cable. Now, lift the black plastic connector upwards, out of the connector housing. On my first attempt, I tried to push it out sideways—this will not work, you have to lift it.


Connectors J804 and J801 use a flat-ribbon cable, which is VERY delicate. Be careful in working with tools in that area. The locking mechanism is also different. Note the black piece of plastic; it folds upward. While you can operate it with tools, I found flipping it upwards with a finger much easier. Very carefully remove both ribbon cables now.


Remove these four screws holding the PCB in place.


Lift the main PCB upwards at a slight angle. You have to overcome the suction force of the GPU and memory TIM, wiggling helps.


Mission accomplished!

Graphics Card Cooler Back

NVIDIA's cooler uses a large vapor chamber base paired with four heatpipes. A 85 mm fan is installed on each side.


To further take apart the heatsink assembly, you have to push these three pins towards the inside. A fine screwdriver or piece of plastic works well.


The pins lock into these grooves that have been cut into the heatsink frame.




On the frame, you will find an LED for the center lighting, and another one that illuminates the GeForce logo. Very impressive, another engineering masterpiece.
